Maximus VIII Ranger continously attempts to boot, fails. Code 00, this is the replacement motherboard

[Nimic]

Hello,

I am running out of ideas, getting a bit desperate at this point.

Recently I bought the following:

ASUS ROG MAXIMUS VIII RANGER
Intel Core i7-6700K Skylake Prosessor
HyperX Fury DDR4 2133MHz 16GB
EVGA GeForce GTX 1070 FTW Gaming

I also have a PSU (Corsair TX850) and a CPU cooler (Corsair H100 - which I read on the internet should fit the 1151 socket as well) that I didn't replace.

The current motherboard is a replacement for one I sent in and got refunded. That one would only boot if I didn't have the graphics card in. If it was in, it would constantly try to start up (the red light would be on all the time if it was getting power), running the fans (including CPU cooler, case fans and the GPU fans) for half a second and briefly showing a 00 code (not assigned). I sent that one in, and the vendor refunded it.

Today I received the replacement, and to my surprise I have a similar but crucially not identical problem. I still get the failure while attempting to boot (with code 00, fans running), but it doesn't matter if I have the GPU in or not. I have tried with or without any and all of graphics card, hard drives and CPU fan unplugged. I have also tried reseating it, tightening screws, loosening screws and running it completely out of the case with just the two power cords connected. Finally, I have tried resetting the CMOS, but only through the button on the motherboard, not the other way. No change.

I had originally dismissed the problem as being my GPU or PSU, because they are both currently running (and have been since my original issues) with my old motherboard/cpu. I dismissed the CPU based on it running without issues with the original motherboard, without the GPU.

Obviously there should be enough wattage, but could there be another issue causing my PSU to have problems with that motherboard? I simply don't see what else it could be at this point, unless they somehow sent me another defect piece of hardware. Seems unlikely.

Is there anything crucial I am possibly missing?

Cheers.

Edit: The problem was the PSU. I replaced it and now it works just fine.

Did you bend pins in the CPU socket installing chip and cooler? 00 (I think its actually D0) means your motherboard cant communicate with your CPU.

There are no bent pins on the socket, I checked very closely. I don't know what to look for on the CPU these days, since it doesn't have the pins, but it doesn't look like there is any obvious problem. In any case, it was working on my previous motherboard. I am fairly sure I got the 00 error there as well when the GPU was in. I am also 99% sure it says 00 and not D0, which is just "Not used" in the list in the manual. Seems strange, but I quadruple checked that last time.

I think d0 and D0 are different, but if there are definitely no bent pins then it isn't that, but if you inspect with a magnifying glass and go across the rows of pins one by one you may find something. And do you mean you ran the CPU without a cooler on? Because that will fry it very quickly. Have you checked the cooler isnt too tight? Even that can bend pins or cause issues. Is a tricky one I admit, but when I read it I immediately thought it sounds like a socket issue. Could be a faulty processor I guess. Also, your cooler isnt actually compatible with that socket or even the previous 1150 one so it could be causing problems?

I only ran the CPU without the cooler very briefly, for a few seconds at a time, just to check if the problem was anywhere there. I basically tried it with only the power cables for the motherboard connected.

Is the cooler really not compatible? I know it isn't "on paper", but I am certain I read that it is actually compatible even so. It certainly fits the motherboard, although whether it is too tight or too loose, tough to say. I doubt that would cause the error though.

I considered the CPU, but it is throwing me for a loop since it was working with my previous faulty motherboard. Since then it has basically been sitting in a cupboard, and I was careful bordering on paranoia when installing it in my replacement. I guess it could be.

Did you try connecting a speaker to the system warning speaker header on the system panel connector to determine if there is a beep code being produced?

Cooler being too tight can definitely cause problems, crushing pins and not allowing certain areas of the chip to communicate. It probably IS compatible as long as it fits the backplate properly tho, but just a thought. I personally havent used that cooler. And can you run the Intel Processor Diagnostic tool on it somehow? Maybe it got damaged by your bad motherboard. You shouldnt have problems that severe unless its hardware I dont think.

I haven't, since I couldn't actually find the "speaker" cable right then and there. My PSU has way too many cables, so it is probably hidden in there somewhere. I haven't had it connected in years, but I am certain my case must have one. I will try it tomorrow.

Unfortunately right now I don't have the opportunity to test my CPU on any compatible motherboard. That would certainly solve quite a few issues... I suppose my CPU might have been damaged. I will have to try to a) get a hold of another compatible motherboard or b) get a hold of a compatible CPU, so I can test either one.

Good luck! Always ready to try to help if you post your progress here. I know what stress it can be!

Just an update, in case anyone has the same problem and comes looking for a solution. In my case, at least, it turned out to be the PSU. I didn't think it would be, since it worked perfectly fine with my old setup (+ new GPU), but I bought a new one anyway since the old one had way too many cables and created a clutter. Now the replacement motherboard and the original CPU work just fine.
